LIGHTING BRACKET Filed May 20 192 WlTNE SE5: 2) #5 M INVENTOR (2/ JacobDym Patented Mar. 10, 1931 UNITED STATES PATENT OFFICE TO POBG'ELIER CORPORATION Application filed May 20,

M invention relates to porcelain lighting brac ets and particularly to brackets provided with a convenience outlet.

One object of my invention is to provide 6 a convenience outlet that shall be rigidly supported on the bracket.

Another object of my invention is to provide a convenience outlet on a bracket in which the supporting structure for the outlet shall be integral with the bracket.

' Another object of my invention is to pro-- vide a convenience outlet for a bracket, in which the outlet shall consist of a minimum number of parts and be relatively simple in construction.

In brackets heretofore provided with a convenience outlet, the outlet consisted of a bayonet plug receptacle which was secured to the bracket by screws or bolts. In some brackets two parallel slots were dis osed in the. base of the bracket through w 'ch the bayonet blades were inserted to enter the re 'stering recesses in the receptacle disposed be ind the slots. receptacle extended through an opening in the base of the bracket and was secured to the bracket by suitable means.

In the construction which I describe herein, the bracket is provided with two parallel slots extending through the baseof the bracket. Behind the slots on the rear surface of the bracket is disposed a artitioned porcelain box integral with the dy of the bracket. The box is separated by the partition into two compartments, each of which contains a jaw contact, member for receiving a corresponding blade contact of the bayonet plug. The walls of the box also support a shelf in each compartment upon which a terminal rests to permit proper connect-ions between the wiring and the jaw contacts. By reason of the box construction being integral with the bracket body, a rigid support is provided thereby for the contact members of the convenience outlet.

The construction is illustrated in the accompanying drawings in which: Fig. 1 is a side elevational view of a bracket provided with a convenience outlet; Fig. 2 is a rear elevational view of the bracket in Fig. 1;

Fig. 3 is an elevational view of the lower portion or the bracket containing the convenience outlet terminals; Fig. 4 is a front elevat-ional view of the supporting structure for the convenience outlet; Fig. 5 is a front elevational "iew of an assembled jaw contact member; Fig. 6 is a side elevational view of the contact shown in Fig. 5; Fig. 7 is a perspective view of an insulating cover; and gig. 8 is a plan view of a spring clip thereor. As illustrated in the accompanying drawings, a light bracket is provided with a base 2, a husk or receptacle 3 for supporting a socket for an electric light, and a convenience outlet 4 to which access may be had through two small openings 5 extending ghrough the lower portion of the bracket ase.

The convenience outlet consists'of a porcelain box or support 6 divided into two compartments 7 and 8 by apartition 9. The inner wall surfaces of the two compartments are provided with horizontal ridges or shelves 10 and 11 upon which contact members or clips 13 are rigidly supported.

The porcelain box orsupport is integral with the porcelain base and thus provides a rigid structure for the convenience outlet. The partition serves to insulate the two contact members from each other and also to provide a support for the inner shelf portions upon which the contacts are secured.

The contacts or clips are rovided to receive the blades of a plug. engagement is made by inserting the blades through the openings 5 in the base of the bracket. In

order to prevent the clips from becoming loose, they are tightly secured to the supporting shelves 10 and 11 by a bolt 14 and a nut 15 which tightens a washer 16 against-the shelves as seats. A second nut 17 cooperates with the nut 15 to secure the tip of a wire connected to the conductors (not shown) provided for the lamp socket.

While the clip may be of any suitable design which will insure a tight sliding fit on the plug blade, the clip which I employ is provided with a bent portion 18 of substantially horse-shoe shape under stress, and

with tips 19 bent back upon themselves to engage each other with a yielding pressure.

he blade when inserted is engaged by the ti s.

After the clips are secured in position, a

fiber cover 20 is placed about the front and sides of the porcelain box and locked in posi- Ltion by a' small spring clip 21.

By means of the porcelain box, a more rigid structure is obtained for the convenience outlet and the contact clips may be more securely anchored in position. Better insulation is obtained since no extraneous metallic anchoring means are required as in other brackets in which a socket is secured to the base. The bracket may be assembled with greater ease and has a minimum number of parts.

My invention is not limited, of course, to the specific construction or design illustrated 0 since modifications may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims.

I claim as my invention 1. As a new article of manufacture, a lighting bracket comprising a hollow shell of porcelain having an integral hollow support with a lateral opening through which contact members may be inserted, there being 0 openin s through the shell communicatin with t e interior of the support, throug which blades of a serviceplu are to be inserted, and projections on the interior of the support to engage the contact members and retain them in position to be engaged by the blades on a service plug.

2. As a new article of manufacture, a light ing bracket comprising a' hollow shell of porcelain having I an integral su port 40 with two chambers therein, each c amber having a lateral opening, there being an opening extending from each chamber through the shell, through which blades of a service plug are to be inserted, and projections on the interior of each chamber to engage the contact members and retain them i in position to be engaged by the blades on a service plug.

I 3. As a new article of manufacture, a wall s lighting bracket comprising a hollow shell 0 porcelain with an opening at the rear thereof, an integral support within the shell having two recesses in its rear face through which contact members may be inserted, there being an opening extending through the shell from each recess, through which blades of a service plug are to be inserted, and projections in each recess to engage the contact members and retain them in position to be enga ed by the blades on the service plug.

n testimony whereof, I have hereunto subscribed my name this 15th day of May, 1926.
